Essentially Homo sapiens are one.

Humans have xx chromosomes for females and XY chromosomes for male.

A man have a little bit of female hormones and woman has a little bit of male hormones.

Most fertility problems arise from imbalances in hormones both gender.

High and low progesterone in males comes with problems.

Same with females.

Low progesterone levels in men can negatively impact fertility, immunity, metabolism, and overall health, including cardiovascular, neurological, and skeletal systems.

High blood prolactin concentration interferes with the function of the testicles, the production of testosterone (the main male sex hormone) and sperm production decrease.

Low testosterone causes decreased energy, sex drive, muscle mass and strength, and blood count (anemia).

High prolactin in a man also means automatic low sperm counts.

Best solution to this addressing micronutrient deficiency, building muscle, avoiding high carbs and inflammatory foods.

Embracing nature, indoor plants, sunlight and grounding.

Goodluck.
